Help with 2007 Radio Wire Harness

Can any one tell me where I can find a wire harness for a toyota prius 2007 to an eclipse cd3200 radio? or am I going to have to re-wire the radio wire harness? Which I really dont want to do, unless I get an extension wire harness but... I looked on ebay and google for the extension wire harness and all I came up with was wire harnesses for priuses up until 2006. Can anyone lead me in the right direction please

Thanks a bunch
